When sulfuric acid is added to marble chips, a chemical reaction takes place in which the acid reacts with the calcium carbonate in the marble to produce carbon dioxide gas. This gas forms bubbles which can create a layer around the marble chips, limiting further contact with the acid and slowing down the reaction. Once the layer of gas forms, the reaction rate decreases, resulting in the rapid reaction coming to a halt.

What happens when dilute sulphuric acid is added to copper oxide?
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
What is observed when copper oxide is added into excess dilute sulphuric acid?
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.
When silver coloured metal is added to dilute sulphuric acid solution?
When silver metal is added to dilute sulphuric acid solution, a redox reaction takes place. The silver metal reacts with the sulfuric acid to produce silver sulfate and hydrogen gas. The reaction can be represented by the following equation: 2Ag(s) + H2SO4(aq) -> Ag2SO4(aq) + H2(g)
What will happen if you put marble in hydrochloric acid?
When marble (calcium carbonate) is placed in hydrochloric acid (HCl), a chemical reaction occurs where the acid reacts with the marble to form calcium chloride, carbon dioxide gas, and water. This reaction will visibly produce bubbles of carbon dioxide gas as the marble dissolves, ultimately resulting in the marble breaking down and disappearing in the acidic solution.
Why is 4 normal sulphuric acid added to the titration flask?
4-nitroaniline, an organic compound, is being titrated with sulphuric acid in the mixture to help solubilize the compound. This aids in the reaction and allows for accurate titration results to be obtained.
What is the reaction when sulphuric acid is added to calcium carbonate?
The reaction is:CaCO3 + H2SO4 = CaSO4 + CO2 + H2O
What is given off by table salt added with sulphuric acid?
Any reaction occur.
What did you observe when concentrated sulphuric acid was added to the reaction mixture?
I think it makes the equation to be more balanced
When zinc is added to sulphuric acid what gas produced?
The gaseous product in this reaction is 'hydrogen' and the salt is zinc sulfate.
What happens when dilute sulphuric acid is added to copper oxide?
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
What is observed when copper oxide is added into excess dilute sulphuric acid?
When copper oxide is added into excess dilute sulphuric acid, it reacts to form copper sulfate and water. Additionally, hydrogen gas is evolved during the reaction.

What type of reaction takes place when sulphuric acid added to barium chloride?
acids and bases always react to give a salt and some water.
Why is 4 normal sulphuric acid added to the titration flask?
4-nitroaniline, an organic compound, is being titrated with sulphuric acid in the mixture to help solubilize the compound. This aids in the reaction and allows for accurate titration results to be obtained.
Which gas is evolved when few pieces of marble is added to dilute HCl?
When marble (calcium carbonate, CaCO3) is added to dilute hydrochloric acid (HCl), carbon dioxide gas (CO2) is evolved due to the reaction between the acid and the carbonate compound. This gas can be observed as bubbles coming out of the solution.
What gas is given off when acid is added to marble chips?
Carbon dioxide gas is given off when acid, such as hydrochloric acid, is added to marble chips (calcium carbonate). This reaction produces bubbles of carbon dioxide gas, which can be observed as effervescence.
